Study summary

The purpose of this study is to assess safety and effectiveness of the p64 MW HPC or p48 MW HPC Flow Modulation Device under prasugrel.

Read the detailed description

Title: Observational Registry With p64 MW HPC in Unruptured Anterior Circulation Aneurysms Under prasugrel

Purpose: To assess safety and effectiveness of p64 MW HPC or p48 MW HPC under prasugrel in consecutive patients with unruptured anterior circulation aneurysms.

Follow-up intervals: Independent follow-ups (after 3 to 6 months and after 12 months and after 24 months) according to site specific standard.

Study population

The target population for this Observational Registry are patients with unruptured intracranial aneurysms suitable for flow diversion on operators' discretion. All patients are tested for the extend of their platelet function inhibition prior treatment using VerifyNow (a point-of-care test).

Patients can be included in the Observational Registry if they meet all of the inclusion and none of the exclusion criteria and have provided written informed consent.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • At least one unruptured sidewall aneurysm in the anterior circulation
  • No implant (e.g., stent) in the target vessel segment
  • Age >18 years and \<80 years
  • Not pregnant and in women of childbearing age, on oral for two years following the procedure
  • No participation in another trial
  • No concomitant disease limiting the to \<2 years
  • No allergy to non-ionic contrast medium or to ASA and P2Y12 receptor antagonists
  • No other neurovascular disorder in the same vascular territory requiring treatment in the foreseeable future
  • Ability and willingness to comply with the medication requirements within the study,
  • Ability to understand the goal and risks of this study.

Exclusion criteria

Exclusion Criteria:

  • Intracranial aneurysm considered not suitable for FD using p64 MW HPC or p48 MW HPC.
  • Aneurysm previously treated with a device in the parent vessel (e.g., stent, flow diverter).
  • Another intracranial procedure scheduled for the following 6 months.
  • Age \< 18 years and > 80 years.
  • Pregnancy possible or confirmed. Patient not able or willing to arrange for 12 months after treatment.
  • Patient not able or willing to adhere to the study protocol.
  • Patient not able or willing to undergo the scheduled follow-up examinations.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

What researchers measure

Primary outcomes

  1. Safety endpoint

    Occurence of ischemic or hemorrhagic stroke. Incidence of ischemic or hemorrhagic stroke in the territory supplied by the treated artery.

    Time frame: Within 30 days after the intervention

Secondary outcomes

  1. Safety endpoint

    Occurence of all adverse events and serious adverse events, related directly or indirectly to the intervention, the used device or the required medication.

    Time frame: Within the first 12 months after the intervention

Other outcomes

  1. Efficacy endpoint

    Complete occlusion or the neck remnant of the target aneurysm(s), identified by DSA (Digital subtraction angiography).

    Time frame: 12 months after the intervention
